摘要
采用外循环处理技术设施对苏州城市河道黑臭水体进行200 d的处理。结果表明,COD和TN、NH_3-N、TP的质量浓度分别降至21.65 mg/L和4.75、1.35、0.23 mg/L,透明度得以提高。除了TN含量外,其他所有水质指标均能达GB 3838-2002地表水IV类水质标准。处理设施具有抗冲击负荷能力,在雨水和新近污染水源汇入的情况下,且能使水质在较短时间内恢复。
An external circulation technology facility was adopted to treat the black and odorous river body for 200 d in Suzhou city. The results showed that the effluent of COD and mass concentration of TN, NH3-N, TP decreased to 21.65 mg/L and 4.75 mg/L, 1.35 mg/L, 0.23 mg/L, respectively, and the transparency was improved. All of the other water quality indexes reached the class IV of Surface Water Quality Standards（GB 3838-2002） except TN. The treatment facility showed strong anti-shock load and could be recovered in a relatively short period of time in the case of collected rainwater and newly polluted water.
